Everyone makes/edits blinkies differently. I learned how to make them completely on my own using Photoshop and Animation shop about 8 years ago. I find the way that I add text to my blinkies to be time-saving and makes blinkie-making pretty easy. When I'm making blinkies I make ONE set of boxes, save it as a blank, copy and paste the text onto the boxes as I do in this tutorial. Then I simply just paste the boxes onto the pixel/the pixel onto the boxes. It's very simple and it's how I'm able to make so many at one time. Anyway, on to the tutorial...
This is a very basic and easy tutorial on adding text to a blank blinkie.I made blanks of a very simple blinkie for you to use (included behind the cut).
Included are pictures to help you figure out where things are.
I haven't written a tutorial in a long time so I hope that you guys find it pretty easy to understand. If you have any questions please feel free to leave me a comment here!
( Tutorial on Adding Text to a Pre-Made Blinkie )
Your blinkie should look like mine once you're finished:

If you want your animation to go faster just Select All and go to Animation > Frame Properties and put a lower number as the display time and save the blinkie.
I'll add this entry to the community memories and there is also a "blinkie tutorials" tag on the community sidebar now. More tutorials to come! :)
